Description
The utility model relates to commercial spring scale scale temperature compensator.
Commercial spring scale hand scale and commercial scale counter scale are a kind of popular, popular measurement instruments, have simple in structure, cost is low, be easy to carry, easy to use, be difficult for cheating, advantage such as durable, be applicable to interim stand, huckster.But also exist shortcomings such as error is big, precision is low.Often the reload temperature compensator is improving its precision in this type of hand scale for people, and the patent No. provides a kind of hand scale of the V-2 of being equipped with type temperature compensator for the patent of ZL94240890.X, though this compensator effect is good, and complex structure, Installation and Debugging difficulty.
The purpose of this utility model provides a kind of precision height, spring scale scale temperature compensator simple in structure.
For achieving the above object, the utility model adopts following solution:
This temperature compensator is made up of control rocking bar, location rocking bar, temp-controlling element, connecting rod and pull bar, and control rocking bar and location rocking bar forward lap, equal in length; The connecting rod lower end is hinged with the control rocking bar, fixedlys connected with the location rocking bar in the lower end of temp-controlling element; One end of pull bar is fixedlyed connected with the temp-controlling element free end, and the other end and small end are hinged.The weight plate of controlling rocking bar one end and spring scale scale in use is slide hinged, and the housing of the other end and spring scale scale is hinged.
The temp-controlling element of this temperature compensator and connecting rod can control rocking bar above, also can control rocking bar below; The control rocking bar can be the angle with 20 °～35 ° of horizontal directions; Also can be in horizontal direction, its amplitude of fluctuation is 20 °～35 °.
The utility model is opposite with temperature error equal and opposite in direction, the direction that the location rocking bar reflects by the actual compensation rate that the control rocking bar provides, and offsets just, reaches the purpose of temperature compensation, compare with existing temperature compensator, simple in structure, Installation and Debugging are easy, the precision height.
The utility model is described in further detail below in conjunction with drawings and Examples.

Wherein: 1, pull bar 2, temp-controlling element 3, connecting rod 4, control rocking bar 5, location rocking bar 6, weight plate 7, gear shaft 8, tooth bar 9, housing
Embodiment:
The utility model is made up of control rocking bar 4, location rocking bar 5, temp-controlling element 2, connecting rod 3 and pull bar 1, control rocking bar 4 forward laps with location rocking bar 5, equal in length, its B end is articulated in a B with housing 9 usefulness axle, during use (referring to Fig. 9), the A end of control rocking bar 4 is slide hinged in the some A of weight plate 6 with tooth bar 8, and rocking bar 5 fixed points in location are articulated in the some A ' (coinciding with the back side of an A) of weight plate 6.One end and the rocking bar 4 of connecting rod 3 are articulated in a G, and an end rigidity of temp-controlling element 2 is riveted on the some G ' of rocking bar 5 (coinciding with a G back side), and the H end of pull bar 1 is riveted on a H with its free end, and the K end is articulated in a K with the other end of connecting rod 3.In this complete temperature compensation mechanism, two rocking bars 4 and 5 sizes, by established angle φ by two rocking bars 4 and 5 with respect to the horizontal plane the position and connecting rod 3 and temp-controlling element 2 with respect to the rigging position of rocking bar 4 and 5, can be divided into four kinds of versions.In these four kinds of forms, each size of component determines that principle and performance are duplicate.Fig. 1 and Fig. 2 have provided first kind of version, and temp-controlling element 2 in this structure and connecting rod 3 are contained in the top of control rocking bar 4, and control rocking bar 4 is 20 °～35 ° with the included angle of horizontal direction.Fig. 3 and Fig. 4 provide second kind of version, and temp-controlling element 2 in this structure and connecting rod 3 are contained in the below of control rocking bar 4, and control rocking bar 4 is 20 °～35 ° with the included angle of horizontal direction.Fig. 5 and Fig. 6 provide the third version, and temp-controlling element 2 in this structure and connecting rod 3 are contained in the top of control rocking bar 4, but control rocking bar 4 in horizontal direction, and its pivot angle amplitude is 20 °～35 °.Fig. 7 and Fig. 8 provide the 4th kind of version, and temp-controlling element 2 in this structure and connecting rod 3 are contained in the below of control rocking bar 4, control rocking bar 4 in horizontal direction, and its pivot angle amplitude is 20 °～35 °.
The principle of work of this temperature compensator is (referring to Fig. 9): when temperature by T
0When being changed to T1, temp-controlling element is swing to the left or to the right just, is given in T
1The angle increment Δ φ of temperature lower link 3, and pass to control rocking bar 4, then be given in temperature T at its A end
1Down, as the maximum rated weighing Wmax of weighing W, i.e. compensation total amount Δ f during W=Wmax
2, rocking bar 4 is according to the ratio of actual weighing W and maximum rated weighing Wmax simultaneously, and promptly ε=W/Wmax provides actual compensation rate Δ f
2', this compensation rate is the temperature error Δ f that A ' end reflects with location rocking bar 5
1Equal and opposite in direction, direction is opposite, i.e. Δ f
2'=Δ f
1, offset just, reach the purpose of temperature compensation, eliminated the precise information of temperature error, pass to the gear shaft 7 that is engaged with through tooth bar 8, the pointer that is contained in its two ends just indicates the accurate weight of weight simultaneously on the scale of front and back.
